This paper reports the sensitivity of thermal and displacement histories predicted by a finite element analysis to material properties boundary conditions directed-energy deposition M4 high speed steel thin-wall part additively manufactured on 42CrMo4 substrate. The model accuracy was assessed comparing simulation results with experimental measurements such as evolving local temperatures distortion numerical history were successfully correlated solidified microstructures measured scanning...
In this work, a 2D-thermal model of laser cladding (also called Directed Energy Deposition) composite coating (316L stainless steel reinforced by hard WC carbide particles) was developed. The temperature field and its time evolution were computed the Finite Element software Lagamine then compared to experimental measurements. Indeed, in related effects high temperatures on particles contact with molten metal resulting microstructure at end fabrication evaluated means different techniques....
Within the large Additive Manufacturing (AM) process family, Directed Energy Deposition (DED) can be used to create low-cost prototypes and coatings, or repair cracks. In case of M4 HSS (High Speed Steel), a reliable computed temperature field during DED allows optimization substrate preheating value other parameters. Such is required avoid failure process, as well high residual stresses. If 3D simulations provide accurate thermal fields, they also induce huge computation time, which...
